The linear magnetoelectric effect can manifest as a change in magnetization in response to an applied electric field in certain materials, reflecting a direct coupling between electric and magnetic orders. This phenomenon enables electric-field-based control and detection of magnetization, providing a foundation for specialized instrumentation and a valuable tool for investigating complex systems.

Several measurement approaches are possible. In our laboratory, we can measure either the AC magnetoelectric effect (AC magnetization induced by an applied AC electric field) or the DC magnetoelectric effect (DC magnetization induced by a DC electric field). See the attached measurements performed on a single-crystal sample of Cr₂O₃.
